Acoustic Zen's Robert Lee, never one to rest on his laurels basking in the success of his Adagio series loudspeakers, has officially lowered the gauntlet with the introduction of his Acoustic Zen Crescendo loudspeaker ($12k). Driven by lofty Halcro electronics, it was obvious from the first note that the Crescendos are serious contender if you're looking for a new reference at around $10k. Substantial indeed at 185 lbs per side, sporting dual 5" long-throw Underhung midrange drivers separated by a horn-loaded ribbon tweeter. The bass section boasts dual 8" long-throw Underhung woofers made of ceramic paper cone. Lee qualifies this, his latest invention as "quite an impressive 3-way transmission-line design." One thing is certain, besides the fact I like the looks, the sound was very impressive as well causing me to sit around much longer than planned. Lee says "Just like the Adagio loudspeakers, don't let the price fool you. The Crescendos are going to make life hard for more expensive designs." After hearing the Crescendos at length here in Denver, there's not doubt they're going to win many hearts.

From the simple to the sublime

    

This is the second time I heard this setup and the second time I left the room scratching my wig wonder-struck. The IsoMike demo showed what "no limiting, no compression, no mixing and no equalization" could sound like in DSD!" This humongous space supported 6 pair of Sound Lab ProStat 922 loudspeakers (behind the Sony SS-AR1s photo above). EMM Labs supplied the DSD playback via their multi-channel DAC8 MK IV and CDSD player. Kimber Select was the cable of choice throughout while AC cords were the Kimber Palladian. Total cost of this rig: $507,288.00. Sound-wise, it was totally awe-inspiring the way it reproduced the sonic landscape so seamlessly and effortlessly using the Sound Lab ProStats in surround no less. Unfortunately, even if I could afford a rig such as this, I wouldn't have the space so that makes this unattainable for most humans who resides in anything short of a castle. My hunch is, the sponsors of this room wanted to make a point of "this is what is musically possible when done correctly." What a shame it has to be so correct and BIG.

Speaking of which...

Artistic Audio Imports garnered perhaps one of the best sounding rooms at the show that featured the outrageously huge and expensive Acapella Triolon Excalibur loudspeakers ($170,500.00). Einstein electronics provided the source as well as amplification and I have to admit as cost prohibitive and vainglorious as this system certainly looked, it nevertheless produced a sound that was utterly magnificent. This was the second time I've had the opportunity to hear that ion-plasma (ozone free) tweeter and I've got to admit it is perhaps one of the purist sounding top-ends I've ever heard.

Atma-Sphere Music System, Purist Audio and the classic horn sound via the Hartsfield loudspeakers put on a big demo in a very large suite. All the virtues of horn sound via output transformer-less amplification; sweet and harmonically rich sounding from wall to wall.

The ClairAudient Line Source Array model 16 ($50k) and Steve McCormick's new line of SMc Audio electronics, featuring his new VRE-1 preamp, really served up the music. Here's a unique line source designed by the late Richard Smith (co-founder of Audience) that employs sixteen 50 mm full-range drivers and boasts a whopping 110 dB efficiency rating. The ClairAudient uses zero crossovers and thus claims very high phase coherency. Prior experience tells me these attributes should translate into an ultra-transparent and seamless sonic portrait. Almost. As much as I enjoyed my time here the sound was a tad on the warmish side of neutral. That said, the sound was the opposite of dry, edgy and fatiguing. There's something special indeed about the ClairAudient LSA 16s that deserve further investigation.
